If you are in EU, do this to play.
Download Proxifier, find a Sock5 Proxy here:http://sockslist.net/ look for type 5.
Go into Proxifier, options, proxy settings, enter the IP and port, go to test, in test settings disable test 2. Aslong as it passes test 1 and the ping test 3, it is good.
Now save the settings from the File menu.

Now exit Proxifier (including the icon in bottom right of taskbar).

Load up the game through the site link, log in, hit East server (least lag for most non-US), as the game is loading up, as soon as it gets past the Vindictus logo before it opens the main client, then open Proxifier.
